Twitter has released its second transparency report, which demonstrated a frightening increase in requests for user data by the US government and ignited serious concerns over privacy and free expression.
The list disclosed data requests from over 30 nations, and revealed that the US government was responsible for 815 of the 1,009 information requests in the second half of 2012 – just over 80 percent of all inquiries.
Twenty percent of all US requests were ‘under seal,’ meaning that users were not notified that their information was accessed.
The overall number of requests worldwide also steadily increased last year, rising from 849 in the January to June 2012 period to 1009 in the July to December 2012 period.
Twitter’s legal policy manager Jeremy Kessel blogged that, “it is vital for us (and other Internet services) to be transparent about government requests for user information.”
“These growing inquiries can have a serious chilling effect on free expression – and real privacy implications,” he wrote.
He went on to express hopes that the publication of the transparency data would be helpful in two ways – “to raise public awareness about these invasive requests,” and “to enable policy makers to make more informed decisions.”
The majority of US requests were subpoenas, which comprised 60 percent of government demands for information. Subpoenas usually seek user information such as email addresses affiliated with accounts and IP logs. A user’s whereabouts can generally be located by the IP address they are using.
Twitter complied with US government requests 69 percent of the time, according to the report.
